Phase 1 - Provide MOXy annotation support equivalent to our XML metadata support

This phase of development involves providing MOXy annotation support equivalent to the existing EclipseLink XML metadata support

Annotations

The following annotations will be targeted in this phase:

Example: XmlReadOnly annotation

The following example will demonstrate how the XmlReadOnly annotation can be applied:

A property can be configured to be read-only via EclipseLink XML metadata as follows:

<xml-attribute java-attribute="salary" read-only="true" />

The equivalent configured via annotations would look like:

package org.example;
 
public class Employee {
    @javax.xml.bind.annotation.XmlAttribute
    @org.eclipse.persistence.oxm.annotations.XmlReadOnly
    public String salary;
}

Following is the proposed XmlReadOnly annotation:

package org.eclipse.persistence.oxm.annotations;
 
@Target({ElementType.FIELD, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
public @interface XmlReadOnly {
    Boolean value();
}

Example: XmlWriteOnly annotation

The following example will demonstrate how the XmlWriteOnly annotation can be applied:

A property can be configured to be write-only via EclipseLink XML metadata as follows:

<xml-attribute java-attribute="privateData" write-only="true" />

The equivalent configured via annotations would look like:

package org.example;
 
public class Employee {
    @javax.xml.bind.annotation.XmlAttribute
    @org.eclipse.persistence.oxm.annotations.XmlWriteOnly
    public String privateData;
}

Following is the proposed XmlWriteOnly annotation:

package org.eclipse.persistence.oxm.annotations;
 
@Target({ElementType.FIELD, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
public @interface XmlWriteOnly {
    Boolean value();
}

Example: XmlCDATA annotation

The following example will demonstrate how the XmlCDATA annotation can be applied:

A property can be configured as CDATA (character data) via EclipseLink XML metadata as follows:

<xml-element java-attribute="characterData" cdata="true" />

The equivalent configured via annotations would look like:

package org.example;
 
public class Employee {
    @javax.xml.bind.annotation.XmlElement
    @org.eclipse.persistence.oxm.annotations.XmlCDATA
    public String characterData;
}

Following is the proposed XmlCDATA annotation:

package org.eclipse.persistence.oxm.annotations;
 
@Target({ElementType.FIELD, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
public @interface XmlCDATA {
    Boolean value();
}
